HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 341,689, dated May 11, 1886.

Application filed January 12, 1886. Serial No. 188,337.

To all whom it may concern.-

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the countyof Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Heel-Nailing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to mechanism forholding a boot or shoe upon the last or heel sup port in an upright position and for forcing the same vertically downward against a plate, for the purpose of compressing the heel-blank or heel against the surface of the outsole of the boot or shoe before it is attached.

It further comprises means for pricking holes in the said compressed heel-blank for feeding the attaching-nails automatically thereto, and for driving them through the compressed heel into the outer and in soles.

It further relates to mechanism for automatically feeding and attaching top lifts t0 the attached heel; also, to devices for automatically supplying the attachingnails.

It further comprises devices whereby upon one movement of the operating-treadle the various operations above alluded to are successively and automatically performed.

Referring to the drawings,Figure 1 is avertical central section of a heel-nailing machine having the features of my invention. Fig. 2 is a cross vertical section. Fig. 8 is a hori zontal section upon the line a: a of Fig. 1 and a plan view of the parts below it. Fig. 4 is an enlarged section of a portion of the mechanism operating the awls and drivers and feed ing the nails. Figs. 5, 6, and 7 are detail views.

A represents the frame of the machine; B, a stationary bed or table. 0 is the jack-post, which supports the last or work support 0.

The jack-post G is attached to a block, 0', which is vertically movable in the bearing a", formed in the bracket or arm 0", extending horizontally from the frame A. This block is moved vertically and held locked by means of a compound toggle operated by a cam. The toggle comprises the link 0, pivoted at 0 to the head of the frame A and at c to the links (No model.)

'0 0 The link a is pivoted at c to the movable block or head 0. The link a is pivoted at 0" to the link 0, which in turn is pivoted at c to the frame A. The links c a are also pivoted at 0 to the sliderod a, and this rod is moved vertically by means of the cam C, which has a cam-groove, c, for the reception of a cam-pin, 0, extending laterally into the same from the rod 0 This cam O" is timed first to move the head a downward to compress the heel-blank upon the sole of the boot or shoe and the heel-support, and to hold it so compressed while the awls are being reciprocated, the attaching-nails fed, and the driveis reciprocated to drive them. The head 0 is then lifted, with the jack and the shoe thereon, by the operation of the cam, and the top lift fed automatically into place, when the cam 0 again operates to move downward the blockc', and consequently the l1eel-support,t0 spank on the top lift, and the head is then immediately lifted by the cam to its original position, unless a heel-trimming device is used, in which case the cam does not operate to lift the head 0' until after the heeltrimming mechanism has been operated. The jack-post O is provided with a screw, 0", for adjusting the jack-spindle and boot or shoe support vertically.

The bed B is provided with a recess orhole, I), having a shoulder, 12, for receiving the templet-plate D. This templet-plate also has a shoulder to bear against the shoulder b, and it is fastened in place byasetscrew, or in any other desirable way. ltis provided with the perforations or holes which correspond in number and arrangement with the member and arrangement of the nails to be driven into the heel to be attached, and it is made removable from the bed B,in order that blocks having other arrangements of holes may be substituted therefor. There is arranged below said bed B a horizontally-sliding carriage, E, which supports two verticallymovable blocks, 6 e. The blocke supports a gang or group of awls, o the upper ends of which enter the holes 6 in the cross-plate 6, attached to the carriage E. Theblock e sup ports the drivers a the upper ends of which extend into the holes o of the block c which is also attached to the carriage. The driverholder block 0 is moved and held away from the block 6 by means ofa spring, 6 A There is arranged below the carriage and in line with thejack-post and templet the head F, which is reciprocated,as hereinafter described, first, to move the awlblocl vertically, and,

s -cond, to move the driver'block vertically as,

they are moved successively over the head.

The carriage E is automatically horizontally moved, to bring the awls and drivers successively in register with the holes in the templetblock D by the cam E on the shaft 6 and the lever c pivoted at e.

The head F is operated by a toggle, ff, slide-barf, and cam f on the main shaftf. The cam is timed to move the toggle and the head upward when the awl block has been brought into position over it, and the awls are forced through the holes in the templet into the heel-blank, and upon the downward movement of the head the awlblock is drawn down by thehead. The carriageE is then moved to bring the driver-l lock over thehead The next upward movement of the head forces the driver-block upward and drives the nails through the holes in the templet and into the heel or sole of the boot or shoe. The head F then comes to rest, and the movement of the carriage E is reversed, and the awl-holder block moved into line for operation upon the next wheel.

In order that the head F may operate to draw the awl-holding block downward, I have formed a dovetail projection,E,at its upper end,which fits the dovetail recess E in the awl-block, the projection and recess being arranged so that the awl-holding block can be moved on and off theprojectiou,while upon the downward movement of the head F the awl-block is caused to be drawn down.

To feed the attaching nails automatically, I have arranged on one side of the bed B a nail-holding block, G, which has holes corresponding in number and arrangement with the holes in the block 6, and it may or may not have a covering-plate similar to that described in the Patent No. 316,894, according to the time of the discharge of the nails into the holes in the block 0 This block 0 is made thick enough to provide holes of sufficient depth for receiving the nails from this nail-holder, and also the upper ends of the drivers. The holes in the nail-holder block are connected with the perforated block 9 by the tubes or passages g, and the blockg is supplied with nails automatically by devices similar to those described in the Patent No. 317,199,0rin theapplication of Towns and myself, filed November27, 1885, Serial No. 184,048. The only difference between the devices described in the said patents for making, cutting, or delivering nails to the nail holder when organized to operate as therein described and when organized to operate in connection with the mechnails are used the nails must be delivered to the nail-carrier block with their points uppen most, and in the machines where the nails are made from wire this result is obtained by sinr ply reversing the cutters.

\Vhen the heel is blind-nailedthatis, provided with a top lift spanked upon the heads or ends of the nails left projecting from the under surface of the heel-I form in the bed above the templeta recess or ways, It, in which isreciprocatedatop-lift-l'eedingplate,H. This plate has two parts, the part h, which forms a portion of the templet, in that it is provided with perforations in continuance of the perforations in the holes of the templetblock D, and a portion, I1 which is impert'orate, and which is adapted to carry from a stack of top lifts, 715, the undermost one to a position to be attached or spanked to the heel. It has a gage-plate, It, which is movable transversely upon the plate by the screw h and the springarm 11", the end h of which is moved backward by a pin, If, as the plate is moved beneath the stack of top lifts h. The stack of top lifts is held in a box, which may have adjustable sides for limiting the size, similar to those described in my Patent No. 289,857, and it has a vertically-movable gate similar to the one therein described for limiting or adjusting the size of the opening through which the undermost top lift is moved by the plate 71%. The plate H is reciprocated at proper intervals by the cam 71 on the shaft 11" and lever h, pivoted at /1"-'.

The main shaftf is connected with the shaft 0" by the gear M m, and with the shaft h by the gear on m. The cam O has a bearing up on the shaftf, but is not revolved thereby. It is provided with a gear, m which meshes with gears m" and m" upon the shafts h" and c", by which it is revolved.

The mechanism for starting and stopping the machine is similar to that described in Letters Patent No. 287,472. and need not further be described here. \Vhen nail making or feeding devices like those above referred to are used, the mechanism employed is automatically setin operation to deliver nails to the nail-holder by the heel-nailing machine, and by means substantially as described in said Patent No. 317,199.

Any form of heelsupport or last may be used, and probably the one used in the McKay heeling-machine, so called, will answer for this purpose as well as any.

In operation the boot or shoe is adjusted upon the last, and the heel-blank placed upon the upper surface of the templet portion It of the plate H, which may have devices for holding it by its edge thereon. The machine is then started, the last is moved downward by the compound toggle upon theheel-blank,compressing it upon the heel end of the sole between the upper surface of the templet and the under surface of the last. The awls are immediately forced upward through the holes in the templet and withdrawn, the carriage ICO IIO

E moved forward, to bring the drivers and attaching-nails in line with the holes in the templet, and the drivers are immediately reciprocated by the movement of the head F, to drive the nails through the templet into the heel and sole of the boot or shoe. The last is then in'n'nediately lifted, and the toplift -carrying plate moved to bring the top lift beneath the heel, when the last is again moved forcibly downward by the compound toggle, to spank atop lift onto the ends of the nails which may have been left protruding from the heel-blank to receive it. The last is immediately raised again to permit the re moval of the boot or shoe, the top-lift plate returned to its normal position to receive another top lift from the stack, and the carriage E moved to bring the awls into position for operation upon the next heel to be attached. This movement of the carriage brings the nailcarrying block 6 beneath the nailholder, and it then automatically receives a load of nails therefrom, and the nail-feeding devices are set in operation,to make or feed and arrange in the nail-holder another load for subsequent delivery to the block if.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.
